Because the lower extreme of water tank front connection post 2 is connected with front longitudinal beam anterior segment 1, the upper end of water tank front connection post 2 is connected with front wheel casing upper longitudinal beam 3, this just connects front longitudinal beam anterior segment 1 and front wheel casing upper longitudinal beam 3 through water tank front connection post 2, like this, when the collision is for example little offset collision, the transmission of impact attenuates backward along the front longitudinal beam, simultaneously, partly impact will upwards transmit front wheel casing upper longitudinal beam 3 and backward on the A post structure of vehicle through water tank front connection post 2, like this, can reduce automobile body front deck frame structure's whole deformation, consequently, this automobile body front deck frame structure can absorb the collision energy well in for example little offset collision when the vehicle collision, promote the security performance.
In the vehicle body front compartment frame structure of the present invention, the water tank front connection column 2 may have various structural forms, and it should be noted that, no matter what structural form the water tank front connection column 2 adopts, it is only necessary to connect the front longitudinal beam front section 1 and the front wheel cover upper longitudinal beam 3 for force transmission. For example, in one structural form of the water tank front connecting column 2, the water tank front connecting column 2 may have a step structure which is arranged at intervals in the vehicle front-rear direction and has a height difference in the vehicle height direction, or in another structural form of the water tank front connecting column 2, as shown in fig. 1, the water tank front connecting column 2 is curved and extended upward and outward in the vehicle height direction and width direction, so that the structure curved and extended upward and outward in the fig. 1 can be formed, so that the transmission of the impact force can be more balanced, the bending point of the water tank front connecting column 2 can be avoided, the resistance and guiding capability of the water tank front connecting column 2 to the impact force can be improved, and the vehicle body can be easily slid in the Y direction.
In addition, the water tank front connection column 2 may be a solid cylinder, or a plurality of sections of cavities are formed in the water tank front connection column 2 and are arranged at intervals along the extending direction of the water tank front connection column 2, or as shown in fig. 1 and 2, a hollow channel is formed in the water tank front connection column 2 and extends from the lower end to the upper end of the water tank front connection column. Like this, through this hollow channel to when biography power, can absorb impact energy more effectively, simultaneously, this kind of cavity passageway can also make water tank front connection post lightweight.
In addition, in an embodiment, as shown in fig. 2, the water tank front connecting column 2 may be formed by welding a first plate 15, a second plate 16 and a third plate 17, a space formed by the first plate 15, the second plate 16 and the third plate 17 is a hollow passage, and the hollow passage may be oval, circular or rectangular or in other shapes.
Therefore, compared with a plastic part and a single-layer sheet metal part type water tank front connecting piece in the prior art, the hollow channel of the water tank front connecting column 2 is a cavity with a closed cross section, and rises in the Z direction (the height direction of a vehicle), expands in the Y direction (the width direction of the vehicle), and extends in a curve bending manner, so that the resistance and the guiding capacity of the water tank front connecting column to the impact force can be further improved, and the vehicle body can easily slide in the Y direction.
In the vehicle body front compartment frame structure of the present invention, the water tank front connection column 2 may include a rear section that may serve as the water tank rear connection column 14, so that the upper end of the water tank front connection column 2 may be directly connected to the front wheel house upper longitudinal beam 3, or the upper end of the water tank front connection column 2 may be connected to the front wheel house upper longitudinal beam 3 through the water tank rear connection column 14.
As shown in fig. 1, a wheel house front reinforcement beam 5 is provided at the front end of the front wheel house 4, the lower end of the wheel house front reinforcement beam 5 is connected to the front side member front section 1, and the upper end of the wheel house front reinforcement beam 5 is connected to the water tank front connection column 2. That is, the upper end of the wheel house front reinforcement beam 5 may be directly connected to the water tank front connection pole 2, and when the rear end of the water tank front connection pole 2 includes the water tank rear connection pole 14, the upper end of the wheel house front reinforcement beam 5 is connected to the water tank rear connection pole 14. Like this, when water tank front connection post 2 transmits the impact to longeron 3 on the wheel casing, partly impact can be through the wheel casing front stiffening beam 5 transmission to the front longitudinal anterior segment downwards, and simultaneously, a part of the impact of the 1 backward transmission of front longitudinal anterior segment can be through the reverse transmission upwards of wheel casing front stiffening beam 5, thereby the impact through the wheel casing front stiffening beam 5 transmission downwards and upwards will offset, that is, wheel casing front stiffening beam 5, water tank front connection post 2 and front longitudinal anterior segment 1 form a triangular closed power transmission structure, thereby promote anti striking nature. In addition, since the wheel house front reinforcement beam 5 is provided in the front portion of the front wheel house 4 in the front-rear direction of the vehicle, the entire deformation of the vehicle front compartment frame can be reduced, and therefore, this vehicle front compartment frame structure can favorably absorb collision energy at the time of vehicle collision, for example, in a small offset collision, and improve the safety performance.
In addition, a cavity may be formed between the wheel house front reinforcement beam 5 and the front wheel house 4, for example, as shown in fig. 2, the wheel house front reinforcement beam 5 includes a groove extending from an upper end to a lower end, so that an extended passage from the upper end to the lower end is formed between the front end of the front wheel house 4 and the wheel house front reinforcement beam 5, and thus, passage walls of the extended passage, that is, the wheel house front reinforcement beam 5 and the cover wall of the front wheel house may be deformed accordingly to further absorb the impact energy.
As shown in fig. 1, a wheel house rear reinforcement beam 6 is provided at the rear end of the front wheel house 4, the lower end of the wheel house rear reinforcement beam 6 is connected to the front side member front section 1, and the upper end of the wheel house rear reinforcement beam 6 is connected to the front wheel house upper side member 3. Like this, when water tank front connection post 2 was gone up longeron 3 transmission impact to the front wheel casing, some impact can be through 6 downward transmissions to the front longitudinal anterior segment of wheel casing rear stiffening beam, and simultaneously, some of the impact of 1 backward transmissions of front longitudinal anterior segment can be through the reverse transmission that makes progress of wheel casing rear stiffening beam 6, thereby the impact through 6 downward and the transmission that makes progress of wheel casing rear stiffening beam will offset, that is, wheel casing rear stiffening beam 6, water tank front connection post 2, front wheel casing upper longitudinal beam 3 and front longitudinal anterior segment 1 form a closed biography power structure, thereby promote anti impact. In addition, since the wheel house rear reinforcement beam 6 is provided at the rear of the front wheel house 4 in the front-rear direction of the vehicle, the entire deformation of the vehicle body front compartment frame can be reduced, and therefore, the vehicle body front compartment frame structure can well absorb collision energy at the time of vehicle collision, for example, in a small offset collision, and improve the safety performance.
For example, in one embodiment, as shown in fig. 1, a wheel house front reinforcing beam 5 is provided at the front end of the front wheel house 4, the lower end of the wheel house front reinforcing beam 5 is connected to the front side member front section 1, and the upper end of the wheel house front reinforcing beam 5 is connected to the water tank front connecting column 2. The rear end of the front wheel casing 4 is provided with a wheel casing rear reinforcing beam 6, the lower end of the wheel casing rear reinforcing beam 6 is connected to the front longitudinal beam front section 1, and the upper end of the wheel casing rear reinforcing beam 6 is connected to the front wheel casing upper longitudinal beam 3. Thus, as shown in fig. 1 and 4, the wheel cover front reinforcing beam 5, the water tank front connecting column 2 and the front longitudinal beam front section 1 form a triangular closed force transmission structure, the wheel cover front reinforcing beam 5, the front wheel cover upper longitudinal beam 3, the wheel cover rear reinforcing beam 6 and the front longitudinal beam front section 1 form a quadrilateral closed force transmission structure (see a dotted line quadrilateral in fig. 4), and meanwhile, the wheel cover rear reinforcing beam 6, the water tank front connecting column 2, the front wheel cover upper longitudinal beam 3 and the front longitudinal beam front section 1 form a large closed force transmission structure. Therefore, the overall deformation of the front cabin frame of the vehicle body can be further reduced through the three connected closed force transmission structures (the force transmission paths can be seen as solid line arrows in fig. 4 and dotted line arrows in fig. 5), so that the quantity of the force transmission paths is increased, the transmission and dispersion of the impact force are accelerated, parts on the force transmission paths are reinforced, the resistance to impact is enhanced, the vehicle is guided to slide in a lateral offset mode in the collision, the safety of the vehicle and passengers is protected, meanwhile, the rigidity of the shock absorber mounting structure on the front wheel cover is improved, the vibration is reduced, and the running quality of the whole vehicle is improved.
In addition, as shown in fig. 1, the front-side member front section 1 is connected with a front-side member rear section 7, and the front-side member rear section 7 may be connected to the center floor of the vehicle or to a rocker beam of the vehicle; the front cabin frame structure of the vehicle body comprises a front wall plate 8 connected with a front longitudinal beam rear section 7 and a front wheel cover upper longitudinal beam 3; wheel house back stiffening beam 6 is connected with preceding bounding wall 8, and the lower extreme of wheel house back stiffening beam 6 is connected in front longitudinal back 7, and like this, preceding bounding wall 8 and front longitudinal back 7 can share a part of impact, simultaneously, because the above-mentioned closed biography power structure that wheel house back stiffening beam 6 formed, can reduce the invasion volume of preceding bounding wall 8 to the car rear direction.
In addition, a cavity may be formed between the wheel house rear reinforcement beam 6 and the front wheel house 4, for example, the wheel house rear reinforcement beam 6 includes a groove extending from an upper end to a lower end, so that an extending passage is formed between the rear end of the front wheel house 4 and the wheel house rear reinforcement beam 6 from the upper end to the lower end. In this way, the channel walls of the extension channel, i.e., the shroud walls of the wheel shroud rear reinforcement beam 6 and the front wheel shroud, can be deformed accordingly to further absorb the impact energy.
In addition, in the case where the dash panel 8 is included, the wheel house rear reinforcement beam 6 may be connected between the dash panel 8 and the rear end of the front wheel house 4 so as to enclose an extension passage extending from the lower end to the upper end.
In addition, referring to fig. 1 and 2, the outside of the front end of the front side member front section 1 includes an outwardly enlarged support portion 9, and the lower end of the tank front connection pillar 2 is connected to the outwardly enlarged support portion 9. In this way, the outward expansion support portion 9 increases the overlapping area of the front side member front section 1 and the barrier boundary 20 during a small offset collision, and referring to the embodiment shown in fig. 3, the front end plate 18 is connected to the front end of the front side member front section 1 and extends outward in the width direction of the vehicle, and the outward expansion support portion 9 is connected between the front end plate 18 and the front side member front section inner plate 19 of the front side member front section 1, so that the impact force borne by the impact beam and the energy absorption box can be guided and decomposed to the front side member front section, and at the same time, the energy absorption box is effectively supported, and the front side member is prevented from being bent under the impact of the collision.
In addition, the outwardly-enlarged support portion 9 may have various shapes, for example, a square or a rectangular parallelepiped, or, as shown in fig. 3, the outwardly-enlarged support portion 9 may have a triangular shape, for example, as shown in fig. 1 and 2, the outwardly-enlarged support portion 9 is a U-shaped plate 10, and both side panels 11 of the U-shaped plate 10 have a triangular shape in which one open side of the U-shaped plate 10 is connected to the front-side-member front section 1 and the other open side of the U-shaped plate 10 faces the front of the vehicle. Therefore, the triangular outward-expanding support part 9 can form a stable triangular cavity support between the front end plate 18 and the front longitudinal beam front section inner plate 19 of the front longitudinal beam front section 1, so that the impact force borne by the anti-collision beam and the energy absorption box can be guided and decomposed to the front longitudinal beam front section more stably and reliably, and meanwhile, the energy absorption box is more effectively supported, and the front longitudinal beam is prevented from being bent under the impact of collision.
The front end plate 18 may cover the open ends of the front-side-member front section 1 and the triangular outward-enlarging support portion 9 and extend outward in the vehicle width direction.
In addition, as shown in fig. 1, the front side member front-end outer panel and the front side member front-end inner panel may be welded together to form a front side member front-end 1 having a cavity. In addition, the front side member front-end inner panel 19 is designed to have a tapered structure in which the front end is wider and the rear end is gradually narrowed in the vehicle front-rear direction (X direction), so that a smooth transition can be formed with the triangular outward expanding support portion 9. Like this, can decompose the impact guide that crashproof roof beam, energy-absorbing box bore to the front longitudinal anterior segment on, wide front end provides enough support for crashproof roof beam, the throat structure of the wide rear end of front end constriction gradually to and from the outside X of expanding the supporting part to front longitudinal anterior segment inner panel 19 of triangle-shaped to the gentle transition, with the impact of can more steadily passing backward.
Further, as shown in fig. 3, the vehicle body front compartment frame structure includes an impact beam 12 in which an energy absorbing structure 13 such as an energy absorbing box is provided between the front of the front side member front section 1 and the front of the outwardly enlarged support portion 9 and the impact beam 12, wherein the end portion of the impact beam 12 extends outwardly beyond the energy absorbing structure 13 in the vehicle width direction. Thus, as can be seen from fig. 3, by enlarging the support portion 9 outward in the vehicle width direction, the width L1 of the energy absorbing structure 13 can be made significantly larger than the width L2 of the front side member front section 1, while, since the end portion of the impact beam 12 extends outward beyond the energy absorbing structure 13, both the energy absorbing structure 13 and the impact beam exceed the fillet area of the 25% offset impact barrier boundary 20 and cover the straight barrier portion. In this way, the overlap area of the impact beam and the offset barrier can be increased to increase support to guide the vehicle Y to side slip after the vehicle impacts the contact barrier.
Furthermore, the present invention provides a vehicle provided with the vehicle body front compartment frame structure described in any of the above. Thus, as described above, the vehicle can absorb the collision energy well at the time of collision, for example, in a small offset collision, and the safety performance of the vehicle is effectively improved.
